The Rokolub AD range of PCC are ash-free EP / AW – additives based on phosphate ester, for lubricants and functional fluids. Due to their excellent properties in reducing friction and wear, these products are the perfect choice for high loads.

The Rokolub AD-series prevents the welding of surfaces sliding on each other under extreme conditions. The products provide protection against excessive tool wear caused by abrasion and ensure that a lubricant film is formed on the metal surface.

Rokolub AD 246 Ultra for example, is a product of the Rokolub AD series and is a tert-butylphenylphenylphosphate with a very low content of free TPP (triphenylphosphate).  The product is only classified as WGK 1. It is characterized by low water content and low acid number, which ensure permanent stability of the product parameters. Due to its high phosphorus content, it has properties that are essential for the lubricating oil industry. Rokolub AD 246 Ultra is used in industrial oils such as hydraulic fluids, compressor oils, turbine oils, gear oils or in car oils or gear oils.
